GOST 17314-81 PDF

Full title and description

GOST 17314-81 — Devices for fastening thermal insulation of steel vessels and apparatus. Construction and dimensions. Technical requirements. This national standard specifies standard designs, dimensions and technical requirements for devices (pins, brackets, clamps and related welded fittings) used to fasten thermal insulation on steel pressure vessels and process apparatus.

Abstract

This standard defines families of standardized fastening devices for thermal insulation of steel vessels and apparatus, giving constructional forms, dimensional series, permissible materials, placement recommendations and technical acceptance requirements. It is intended to ensure interchangeability, reliable fixation of insulation materials and compatibility with welded vessel construction practices.

Scope

GOST 17314-81 applies to the design and dimensional series of devices intended for fastening thermal insulation to steel vessels and apparatus used in industry (for example pressure vessels, heat exchangers and process equipment). It covers principal construction forms of pins, staples/brackets and welded fittings, dimensional limits for common insulation thicknesses, placement patterns on vertical and horizontal vessels, and the basic technical acceptance requirements for these devices. The standard includes mandatory placement guidance for welded elements on vessels (e.g., recommended spacing and offsets for welded parts).

Key topics and requirements

• Standardized types and geometric forms of insulation fasteners (pins, staples, brackets, clips) and their conditional designations.
• Dimensional series matched to common insulation thicknesses and maximum unfolded lengths / masses for each type.
• Constructional requirements for welded and mechanical elements, including basic material and corrosion considerations for attachments exposed to process environments.
• Placement and spacing guidance for welded details on vertical and horizontal vessels (examples in the standard show 500 mm spacing and specific offsets from flanges and welds).
• Technical acceptance criteria and marking/identification of fastening devices to ensure interchangeability and quality control.

Typical use and users

Used by designers and engineers of pressure vessels and process equipment, insulation contractors and installers, manufacturers of fastening hardware (pins, brackets, staples), procurement/specification teams in petrochemical, chemical, power generation and heavy industry, and maintenance departments responsible for insulating plant equipment. Companies producing or supplying insulation anchors and related hardware commonly reference this standard for product dimensions and conformity.

Related standards

Catalogues and vendor listings reference related GOSTs dealing with insulation practices and vessel accessories (examples commonly shown alongside GOST 21944‑76, GOST 26296‑84 and certain GOST 28759 series items). Specific related documents and national rules for pressure vessels and insulation systems should be consulted for complementary requirements.
